Our invention, on the other hand, broadly contemplates the utilization of the suction pulsations in the intake-manifold of an internal combustion engine, to effect the steps-by step rotation of the winding-arbor of a clock-movement.

We claim:

1; In a vacuum-wind automobile clock,

the combination with a clock-movement having a main-springgirbor, of a vacuumchamber adapted to connected with the intake manifold of an internal combustionengine, a diaphragm applied to the said chamber, and connection between the diaphragm and arbor including a springretracte lever whereby the arbor is rotated step-by-step by the movement of the diaphragm, due to the pulsations created in the vacuum-chamber.

2. In a vacuum-wind automobile clock, the combmation with a clock-movement.

having a main-spring-arbor, of a vacuumchamber adapted to be connected with the 25 in-take manifold of an internal combustion engine, a diaphragm applied to the said chamber and operated thereby, ing operating-lever connected with the said diaphr gm, a spring connected with the said lever o operate the same in op sition to the movement thereof by the said iaphragm, a pawl carried by the said lever, a ratchetwheel engaged b the said pawl in the oscillation of the sai lever, and gearing between the said ratchet and the main-spring-arbor, whereby the same is turned bythe oscillations of the lever, due to the movement of the diaphragm under the pulsations of the vacuum.

In testimony whereof, we have signed this specification 1n the presence of two subscribing wi'tnesses.
